The network struck a “long-term deal” for 48,000 square feet at Ruben Companies’ 42-story office tower, The Real Dealreported yesterday. CBS currently occupies the 10th and 11th floors, but TRD said it plans to “reshuffle some space” in the building. The length of the lease wasn’t immediately available.

Ruben developed the 600,000-square-foot building in 1968 on land leased for 99 years from the The Shubert Foundation. Then early last year, Ruben purchased the 30,150-square-foot property for $280 million in an off-market sale, Commercial Observer reported at the time.

CBS rents office space in several Midtown commercial towers, including 1633 Broadway, 555 West 57th Street and 1 Worldwide Plaza. The century-old TV and radio conglomerate also owns its headquarters, a 38-story, Eero Saarinen-designed building at 51 West 52nd Street built in 1964.
